do you have a manual for this vehicle .. the mondeo was not released in the USA so i don't have any diagrams .. when i said vacuum hoses in meant for the air intake/throttle body etc. this diagram is for a 3.0L escort just as a reference indicator of what i mean ? .. also could you remove and clean the MAF sensor located on the air filter tube ... i have never seen it cause this sympton but i cannot do any harm to clean it !! let me know
